Why Compress PDFs?

Smaller files are easier to share and store.

Large PDF files can be difficult to email, slow to load, and take up valuable storage space. Compressing your PDFs makes them easier to share via email and reduces upload/download times.

Our browser-based compression removes unnecessary metadata while preserving document quality.
